The value of van der Waals constant a for the gases O2, N2, NH3, and CH4 are 1.360, 1.390, 4.170, and 2.253L2atmmol−2, respectively. The gas which can most easily be liquefied is
A compressed cylinder of gas contains 1.50×103 g of N2 gas at a pressure of 2.0×107 Pa and a temperature of 17.1∘C. What volume of gas has been released into the atmosphere if the final pressure in the cylinder is 1.80×105 Pa ? Assume ideal behaviour and that the gas temperature is unchanged.
A bubble of gas released at the bottom of a lake increases to four times its original volume when it reaches the surface. Assuming that atmospheric pressure is equivalent to the pressure exerted by a column of water 10 m high, what is the depth of the lake?
A manometer attached to a flask contains with ammonia gas have no difference in mercury level initially as shown in diagram. After sparking into the flask, ammonia is partially dissociated as 2NH3 (g)→N2 (g)+3H2 (g) now it have difference of 6 cm in mercury level in two columns, what is partial pressure of H2 (g) at equilibrium?
A balloon of diameter 21 meter weight 100 kg. Calculate its pay-load, if it is filled with He at 1.0 atm and 27∘C. Density of air is 1.2 kg m−3 . (Given : R=0.082 L atm K−1mol−1)
van der Waal's gas equation can be reduced to virial eqation and virial equation (in terms of volume) isZ=A+VmB+Vm2C+……..
where A =first virial coefficient, B=second virial coefficient ,C = third virial coefficient. The third virial coeffdient of Hg(g) is 625 (cm2/mol)2. What volume is available for movement of 10 moles He(g) atoms present in 50 L vessel?
